文件 `./00000000000000000849.xlog` 没有正确关闭

file `./00000000000000000849.xlog` wasn't correctly closed

当我尝试启动我的 tarantool 时,在日志中看到这条消息:

2016-03-28 17:42:14.813 [31296] main/101/ia.lua C> log level 4

这是什么意思?

此消息表示 Tarantool 没有在关机时写入文件结束标记,而它通常会这样做。这可能发生在崩溃或硬重置之后,换句话说,任何类型的非正常服务器关闭。这样的消息是无害的,它警告您自上次启动以来一些最后的交易可能没有刷新到 WAL。
